Because he’s a bit crap? Hard to judge on the International scene but he looked no better than any of the other Canadian players at the World Cup. There was no spark at all and before you say but he plays for Canada… likewise Bale played for a woeful Welsh side yet he always stood out.
David doesn’t have any stand out qualities, he can hold the ball up and he’s good at penalties but he’s got average finishing, he’s not particularly quick and he lacks those moments of brilliance which in the EPL can be the difference between 1 and 3 points. At a reported €70m? no chance. Look at Openda, he would have been ideal yet he went to Leipzig for €38m… David isn’t worth nearly double what Openda went for.
